Systematics & Distributions

Plowmanianthus is a member of the subtribe Dichorisandrinae of the tribe Tradescantieae of the flowering plant family Commelinaceae. It has 5 species and 2 subspecies, all of which were described with the circumscription of the genus itself by Hardy and Faden (2004). Proceeding from the north to south and southeast of the genus's distribution, the taxa are as follows.

Taxonomy

The genus is named in honor of Timothy Plowman (1944–1989), an American ethnobotanist best known for his intensive work over the course of 15 years on the genus Erythroxylum , and the cultivated coca species in particular. [2] It was first described and published in Syst. Bot. Vol.29 on page 316 in 2004. [1]

Morphology

Rosette, typically unbranched herbs with somewhat succulent, strap-shaped leaves. In the wild, plants grow on the floor of primary rainforests, shallowly rooted in the humus-rich and leaf-litter layers.

Plowmanianthus resembles its close relative, the epiphytic genus Cochliostema , but is smaller (its leaves reach only to ca. 30 cm in length) and is not epiphytic. Its flowers are also much smaller, lack the spirally coiled anthers of Cochliostema, and are usually cleistogamous (i.e., they usually never open).
